Definitions
- the present invention relates to highly viscous nets of a surprisingly high degree of polymerizapolymerization products and to a process of pren a d y e ng o ut o s of ahigh Viscosity and Daring them.
- (2) polymerization products of a very good solu- This application is a continuation-in-part of bility in the same solvents in which also the lower application serial No. 32,467. filed July 20, 1935. polymeric homologues are soluble.
- Mixed peroxides of organic carboxylic acids with fatty acids containing at least 16 carbon atoms are likewise useful, for instance the mixed peroxide stearic acid and succinic acid.
- taining for instance the presence of a solvent or a diluent, temperature, proportion oi the catalyst (for instance about 0.05 to 4 per cent. calculated upon the monomeric compound to be polymerized) and the like,-the course of the polymerization and the properties of the final product may be varied. It is advantageous to carry out the polymerization at about the boiling point of the vinyl ester.
- merization degree of at least about 600.
